What does purulence mean?
Purulence is a formal medical noun meaning the presence or accumulation of pus in or on body tissue. Pus is a thick, usually yellowish fluid that may form as tissue responds to inflammation, injury, or infection. Its presence can indicate that an inflammatory process has become suppurative, although purulence by itself does not necessarily establish the cause or the presence of a particular pathogen. In clinical descriptions, the term is often modified by a word such as “discharge,” “material,” or “infection.” It appears in reports, laboratory observations, and discussions of wounds, abscesses, and affected joints or organs. For most speakers, the shorter and more familiar word “pus” is preferable in ordinary conversation. Purulence is also easily confused with the adjective “purulent,” which describes something containing or producing pus. The distinction is grammatical: purulence names the condition, whereas purulent characterizes it.

Etymology of purulence
Purulence entered English in the late Middle English period from Latin purulentus, meaning “containing pus” or “pus-filled.” The Latin adjective was formed from pus, the source of the English words pus and pustule. Its development reflects the long-established medical distinction between pus and the bodily process by which it forms.
